Two "generic hygrostats" possible?

Have two humidifiers with Shenzen plug and Devolo humidity sensor here. Found the official page about “Generic Hygrostat” and placed two chapters into the configuration.yaml. Not errors reported, but nothing shows up, nothing appeared after full restart. Where to look for the result?

generic_hygrostat:

  • name: V-Schlafzimmer
    humidifier: switch.venta_schlafzimmer
    .
    .
    etc

generic_hygrostat:

  • name: V-Wohnzimmer
    humidifier: switch.venta_wohnzimmer_2
    .
    .
    etc

I have multiple instances of generic hydrostats with no issues, but you cannot have two entries of generic_hydrostat in the configuration.yaml. Instead, try something like this:

generic_hygrostat:

  - name: V-Schlafzimmer
    humidifier: switch.venta_schlafzimmer
    .
    .
    etc

  - name: V-Wohnzimmer
    humidifier: switch.venta_wohnzimmer_2
    .
    .
    etc
